User wearable personal/medical information device

Abstract

A wearable personal/medical information device includes a data display with an associated legend display. A memory stores items of personal and/or medical information relating to the person wearing the device. Upon operation of a switch, the stored information is displayed with the personal/medical information indicated by the data display, and a corresponding legend indicated by the legend display. In a preferred embodiment, certain data such as medical information is preset in a read only memory, and other data which the user may change from time-to-time is stored in a read/write memory.

What is claimed is: 
     
       1. A personal/medical information device capable of being carried on a person, comprising: display means including   information display means for providing a display of items of vital personal or medical information pertaining to the person, and   legend display means for displaying items of identifying legends in association with the items of vital information displayed by said information display means;   operate switch means for initiating displays of said items of vital information and said items of identifying legends by said display means;   storing means including   detachably mountable read only memory means for storing at certain first address locations preset items of vital personal or medical information data and preset items of associated legend data, wherein items of items of vital information data and associated legend data can be read out for display from the first address locations of the read only memory means, and read/write memory means for storing at certain address locations different from said first address locations, items of other information data and associated items of identifying legend data that can be set and updated by the person, and including data input means coupled to the read/write memory means for enabling the person to set and update only the other information and associated legend data, wherein said items of other information and associated legend data can be read out for display from the second address locations of the read/write memory means; and   processor means responsive to said operate switch means for reading out said items of vital information data, other information data and associated identifying legend data, selectively from one of said first address locations of the read only memory means and said second address locations of the read/write memory means, and for enabling the display of the selected information data and legend data by said display means.   
     
     
       2. The information device according to claim 1, wherein said data input means includes a counter for producing time-sequenced numeric data for display by said display means, and input switch means for causing character data to be set at said certain addresses in said read/write memory means, wherein the character data corresponds to the numeric data displayed at a time when said input switch means is operated by the user. 
     
     
       3. The information device according to claim 1, wherein said read only memory means comprises a programmable read only memory. 
     
     
       4. The information device according to claim 1, wherein said processor means includes means for displaying each of said items of information data and identifying legend data in a determined time sequence on said information display means in response to a single actuation of said operate switch means by a user. 
     
     
       5. The information device according to claim 1, wherein said operate switch means includes manual step display button means for displaying legend data and information data stored in both of said read only memory means and said read/write memory means, on said legend and said information display means, respectively, in a determined order upon successive operations of said step display button means. 
     
     
       6. The information device according to claim 1, including heart rate monitor means for calculating a monitored heart beat rate, and for displaying the calculation result on said display means. 
     
     
       7. The device of claim 1, wherein said read only memory means is adapted so that the stored items of information data and legend data are incapable of alteration by operation of the device.
